The swing frequency function is applicable to the textile and chemical fiber fields and the applications
where traversing and winding functions are required.
The swing frequency function means that the output frequency of the inverter swings up and down
around the central of set frequency. The trace of running frequency at the time axis is shown in the
figure below, of which the swing amplitude is set by P09.15. When P09.15 is set to 1, indicating the
swing amplitude is 0, the swing frequency is disabled.
Fig 6.9-3 Schematic diagram for swing frequency work principle
Swing frequency set method is used to set swing amplitude reference quantity.
For central frequency (present set frequency) is relative to variable swing system. Swing amplitude
changes according to central frequency changing.
Relative to max frequency is fixed swing amplitude system, the swing amplitude is fixed.
Swing amplitude: the frequency is restraint by upper/lower limit frequency.
Swing amplitude relative to central frequency: swing amplitude AW=central frequency*swing
amplitude P09.15.
Swing amplitude relative to max frequency: swing amplitude AW=max frequency*swing amplitude
P09.15.
Swing amplitude relative percentage set by Jump frequency amplitude P09.16, actual jump
amplitude=swing amplitude AW*jump frequency amplitude P09.16.
Swing frequency rising time: the time needed run from the lowest point of swing frequency to the
highest point.
Swing frequency falling time: the time needed falling from the highest point of swing frequency to the
lowest point.
